Claim 1

A SOLAR CELL COMPRISING (1) A BODY OF SEMICONDUCTOR MATERIAL, SAID BODY HAVING A FIRST-TYPE OF SEMICONDUCTIVITY, SAID BODY HAVING A RESISTIVITY OF FROM ABOUT 4 TO 10 OHM-CM. WHEN SAID FIRST TYPE OF SEMICONDUCTIVITY IS PTYPE AND FROM ABOUT 1 TO 20 OHM-CM. WHEN SAID FIRSTTYPE OF SEMICONDUCTIVITY IS N-TYPE, SAID BODY HAVING OPPOSITELY OPPOSED MAJOR SURFACES, (2) AN EPITAXIAL LAYER DISPOSED ON ONE OF SAID OPPOSITELY OPPOSED MAJOR SURFACES OF SAID BODY, SAID EPITAXIAL LAYER BEING THIN RELATIVE TO THE THICKNESS OF SAID BODY, SAID EPITAXIAL LAYER HAVING A SECOND-TYPE OF SEMICONDUCTIVITY, SAID EPITAXIAL LAYER HAVING A RESISTIVITY OF FROM ABOUT 100 TO 1000 OHM-CM., SAID EPITAXIAL LAYER BEING UNCOMPENSATED,(3) A LARGE AREA ELECTRICAL CONTACT, SAID LARGE AREA ELECTRICAL CONTACT BEING DISPOSED ON THE OTHER SAID OPPOSITELY OPPOSED MAJOR SURFACE OF SAID BODY AND SUBSTANTIALLY COMPLETELY COVERING SAID SURFACE, SAID LARGE AREA ELECTRICAL CONTACT FORMING AN OHMIC ELECTRICAL CONTACT WITH SAID BODY OF FIRST TYPE SEMICONDUCTIVITY, (4) ANOTHER ELECTRICAL CONTACT, SAID ANOTHER ELECTRICAL CONTACT BEING DISPOSED ON A SURFACE OF SAID EPITAXIAL LAYER, SAID ANOTHER ELECTRICAL CONTACT FORMING AN OHMIC CONTACT WITH SAID EPITAXIAL LAYER, SAID ANOTHER ELECTRICAL CONTACT BEING OF A SUBSTANTIALLY SMALLER AREA THAN THE SURFACE UPON WHICH IT IS DISPOSED.
